June’s Full Moon happens at 9:08 P.M. EDT, simply over a day after the summer time solstice marked the start of that season within the Northern Hemisphere. June’s Full Moon can also be known as the Strawberry Moon, and you may catch it rising reverse the Solar, peeking over the jap horizon lower than half an hour after the Solar units within the west. The Full Moon all the time rises round sundown, in truth, merely due to the geometry that permits us to view the totally illuminated face of our satellite. Because of this the sooner or later your sundown, the sooner or later your moonrise as nicely. Far northern latitudes won’t see sundown and moonrise till close to or after midnight.
Though the title “Strawberry Moon” conjures up pictures of a pink-hued Moon, Luna will look as ivory as ever as she sails by means of the sky. In the event you discover the face of the Moon appears yellow or golden because it rises, that is basically a trick of the sunshine that happens for a similar motive dawn and sundown are tinged yellow, orange, or crimson — the Moon’s mirrored mild should journey by means of extra of Earth’s environment close to the horizon to succeed in us, which preferentially scatters away shorter (bluer) wavelengths of sunshine. The impact will reduce because the Moon rises increased within the sky, returning it to white.

Inside two hours of sundown, asteroid 2 Pallas is excessive within the east, spending some 20′ due east of the recurring nova T Coronae Borealis tonight. Everybody’s eyes are on this fascinating star this summer time; usually glowing round magnitude 10, it’s anticipated to briefly flare up into naked-eye vary and attain magnitude 2, roughly the identical brightness as Polaris, the North Star.
However let’s begin with Pallas, which itself presently glows at ninth magnitude, only a bit brighter than T CrB. It’s been touring in a southwestern arc by means of Corona Borealis and is now approaching the border of neighboring Serpens Caput, crossing into that constellation in only a few days. For a brighter signpost to seek out it, you possibly can first find Epsilon (ϵ) CrB, at magnitude 4.1, and middle your scope there. Then, flip off your monitoring. Lower than 10 minutes later, Pallas ought to sit centered in your eyepiece.
Lower than half a level to Pallas’ west tonight is T CrB. This star final flared in brightness in 1946 and, though astronomers aren’t certain precisely when it would go off once more, present estimates say it ought to expertise one other flare-up between now and September. It’s considered one of fewer than a dozen recognized such recurring novae in our Milky Way, and due to its 80-year cycle, is barely seen to the bare eye as soon as each era or so. So, make sure that to maintain tabs on this gorgeous star within the subsequent few months to make sure you get to witness the occasion of a lifetime!

The Moon passes 1° north of dwarf planet 1 Ceres at 1 A.M. EDT this morning; for some, Luna additionally occults, or passes in entrance of, the rocky ruler of the principle belt. Observers within the central and jap U.S., in addition to jap Canada and northeastern Mexico, will see Ceres utterly disappear behind the Moon for a quick interval
Within the U.S., the pair will rise shut to one another within the constellation Sagittarius late on the twenty second, simply east of the bottom of the Teapot asterism’s deal with. The Moon will likely be hiding Ceres from view throughout the midnight hour.
Each the visibility and timing of the occasion are closely location dependent. The dwarf planet will reappear within the skies above Chicago at 12:19 A.M. EDT and above New York Metropolis at 1:44 A.M. EDT. Observe that Ceres presently shines at Eighth magnitude, so it’s invisible to the bare eye however could be simply captured in binoculars or any small scope.
If you wish to know whether or not the occultation is seen out of your location, you possibly can try the International Occultation Timing Association’s website.
Found in 1801, Ceres is the biggest physique in the principle belt, spanning practically 600 miles (965 kilometers) and containing roughly 1 / 4 of the complete mass in the principle belt. It’s now categorised as a dwarf planet.

Look west after sundown to find the type of Leo the Lion, striding headfirst towards the horizon. Simply beneath his again leg is Comet C/2023 A3 (Tsuchinshan-ATLAS), quickly to develop into what amateurs hope is one of the best comet of the 12 months!
For now, Tsuchinshan-ATLAS is hovering round Tenth magnitude, greatest seen with bigger binoculars or any small- to medium-sized scope. It’s seen for a couple of hours after sundown as Leo units, although the sooner you possibly can catch it the higher, earlier than it sinks too low and turns into embroiled within the thicker, extra turbulent air close to the horizon. You could find the comet tonight simply over 3° south of magnitude 4.1 Sigma (σ) Leonis. Tsuchinshan-ATLAS can also be simply 0.5° southeast of the elliptical galaxy NGC 3640, which ought to glow on the similar magnitude because the comet. Given their related brightnesses, it ought to be fascinating to match and distinction the pair’s shapes, sizes, and constructions.
And, if you’d like a glimpse of the well-known Leo Trio of galaxies, this fashionable grouping is a simple leap 10° due north of the place Tsuchinshan-ATLAS and NGC 3640 sit tonight. The triplet lies near Third-magnitude Theta (θ) Leo, simply 2.5° southeast of this star.

The space round Saturn is sort of busy this morning because the small, Tenth-magnitude moons Tethys and Dione placed on a present. Observe that this commentary will likely be difficult as a result of the moons are fairly faint — bigger scopes will enhance the view, as will photographing or video recording the occasion.
Saturn rises round 12:30 A.M. native daylight time; relying in your location, sure occasions might already be underway. Prior to three A.M. EDT, magnitude 10.6 Dione is seen simply north of the rings on Saturn’s western aspect, closing in on the planet. It disappears into the shadow of the ringed world round 3 A.M. EDT and crosses behind the disk itself some 43 minutes later.
On the similar time, Tethys is transiting Saturn’s giant, shiny disk, transferring from east to west and led by its tiny shadow. The moon is simply skimming the southern fringe of the rings, making it onerous to identify — however an exceptionally rewarding sight when you do. Tethys’ shadow leaves the disk shortly earlier than 3:40 A.M. EDT, whereas the moon continues its journey till roughly 4:20 A.M. EDT. After that, it would proceed pulling away from the planet however stay simply south of the rings — it is perhaps simpler to identify as soon as it leaves the disk, because the distinction between the moon’s faint glow and the darker background will likely be larger.
In the meantime, don’t neglect to search for a lot brighter, Eighth-magnitude Titan. Saturn’s largest moon sits far east of the planet this morning, some 2.7′ due east of the planet’s middle.

Jupiter is bettering considerably within the morning sky. Now some 8° excessive an hour earlier than dawn, the solar system’s largest planet shines at magnitude –2. This morning the planet stands instantly above fainter magnitude 0.9 Aldebaran, the brilliant crimson eye of Taurus the Bull, because the constellation rises within the east.
Jupiter’s 4 Galilean moons are on show this morning as nicely. Ganymede sits to the planet’s east and, so as of nearest to farthest, Io, Europa, and Callisto are to the west. Magnitude 1 Mars lies 24.5° to Jupiter’s west, increased within the sky within the constellation Aries. Roughly halfway between them is Uranus, which requires binoculars to identify, because it glows a faint magnitude 5.8.
Persevering with alongside the morning line of planets, magnitude 7.8 Neptune is 42.7° west of Mars, hanging beneath the Circlet of Pisces. This distant world additionally wants binoculars or a telescope to view. And eventually, magnitude 1 Saturn stands on the finish of the road, one other 10.5° west of Neptune and dominating the faint stars of the constellation Aquarius.
In all, these planets span practically 78° on the sky from Jupiter to Saturn. And as a bonus, the waning gibbous Moon lies an extra 17.7° west of Saturn, including yet one more world to the lineup this morning.

The Moon reaches perigee, the closest level to Earth in its orbit, at 7:30 A.M. EDT. At the moment, our satellite will likely be 229,464 miles (369,287 km) away.
Skimming shortly by means of the sky, the Moon passes 0.08° north of Saturn at 11 A.M. EDT. It’s going to sit to the precise of the ringed planet within the morning sky for observers within the U.S., as this occasion takes place nicely after dawn even on the West Coast. The Moon will maintain transferring quickly alongside the morning lineup of planets, passing near Neptune early tomorrow morning.
This night, let’s examine the progress of considered one of summertime’s most well-known asterisms, the Summer time Triangle, because it rises earlier every evening. By two hours after sundown, the Triangle’s lowest star, Altair in Aquila, is already 30° excessive within the east, shining at magnitude 0.8. To its higher left is magnitude 1.3 Deneb in Cygnus. The Summer time Triangle is capped off by its brightest star, magnitude 0 Vega, to Deneb’s higher proper in Lyra.
On the top of summer time, the Summer time Triangle flies overhead round native midnight. With the airplane of the Milky Way working by means of it, this region is rife with star clusters and nebulae, making it a preferred locale for novice astronomers to level their scopes. Whilst summer time is simply getting began, this area is already excessive sufficient as soon as it will get darkish so that you can start your galactic explorations, so contemplate selecting a couple of targets from the checklist linked above to begin with. We’ll proceed to focus on this area and its many treasures because the season progresses.

The Moon now passes 0.3° north of Neptune at 5 A.M. EDT, simply over 12 hours earlier than our satellite reaches Final Quarter phase at 5:53 P.M. EDT.
If you wish to discover Neptune, this morning’s pairing will make it simpler to find the distant world, which requires optical help to view. Situated in Pisces, Neptune is 5.5° southeast of Lambda (λ) Piscium, the southeasternmost star within the Circlet asterism. However with the Moon a lot nearer, you possibly can merely use Luna as your jumping-off level this morning, although be aware that the faint planet’s mild could also be a bit tougher to select up with the brilliant Moon close by. By a telescope, Neptune spans simply 2″ — see when you can select its “flat” disk among the many close by pinpoint-like stars.
Neptune is now some 2.765 billion miles (4.45 billion km) from Earth, which is why it appears so small. In actuality, the ice giant is sort of 4 occasions as large as Earth and greater than 17 occasions as huge.
